The server exposes only 1 tool (gns_get_compliance_report). The tool has a reasonable 107-character description, but critical quality issues prevent it from scoring higher. The input schema is visible but severely incomplete: the 'agentHandle' parameter is marked as not required (required=false) despite being the primary identifier for a compliance report lookup. No output schema is documented anywhere in the visible source code. The tool description does not explain what fields are returned, when to use it instead of alternatives, or what prerequisites exist. The parameter lacks a proper description in the schema, only a single example is provided ('energy@italy-geiant'), which violates the anti-example principle. The server is HTTP-based (good for protocol readiness), but lacks proper error handling guidance, output schema documentation, and validation constraints. The tool appears to be a thin wrapper around a backend API with no visible defensive input validation or error recovery patterns.

• Document the full output schema as a JSON Schema object. Example: { 'type': 'object', 'properties': { 'trust_score': { 'type': 'number', 'description': 'EU AI Act trust metric (0-100)' }, 'chain_verified': { 'type': 'boolean', 'description': 'Whether the delegation chain is cryptographically valid' }, 'merkle_epoch': { 'type': 'string', 'description': 'Current Merkle tree epoch ID' }, ... } }.
• Remove the example 'energy@italy-geiant' from the parameter description. Replace it with a formal pattern constraint: 'agentHandle (regex: ^[a-z0-9]+@[a-z0-9](?:[a-z0-9-]{0,61}[a-z0-9])?$, max 255 chars): GNS identity handle for the agent'.
• Mark the agentHandle parameter as required=true, or document what the tool returns when no handle is provided (e.g., 'If omitted, returns the compliance report for the calling agent's own identity').
• Add error handling guidance to the tool description: 'If the agent is not found, the response will include error: "agent_not_found" and available_agents: [list]. If trust verification fails, check that the agent's delegation certificate is current via the audit trail.'
• Add examples of error responses to the tool description: 'Errors include: agent_not_found (404), trust_verification_failed (422, retry after delegation renewal), compliance_system_offline (503, retryable).'
• Expand the tool description to explain WHEN to use it: 'Call this to audit an agent's regulatory compliance status before delegating sensitive tasks. Returns EU AI Act alignment metrics and chain-of-custody verification. Requires the agent to have an active GNS identity.'
